The simplest explanation is that Apple only just now got around to increasing the resolution of these elements for the benefit of users who use the cursor-zooming Universal Access feature. But, combined with the fact that some people with Mac Minis connected to TVs via HDMI are reporting that after upgrading to 10.7.3, their system rebooted in HiDPI mode, I can’t help but wonder whether we may be on the cusp of Apple releasing HiDPI Mac displays and/or HiDPI MacBooks. I.e.: retina display Macs.

I’ve been anticipating super-high-resolution Mac displays for over five years, so take my conjecture here with a grain of wishful-thinking salt.
